A. Big Ideas for Small Spaces - The support brackets are suitable for places with limited space and/or requiring spatial flexibility, such as kitchens, laundry rooms, retail/grocery stores, RVs, boats, warehouses, industrial sites, garages, maintenance storage rooms, office/residential storage rooms, etc. They can be applied to table legs or tabletops, used for the folding legs of homemade tables or beds, folding workbench projects, foldable desk extensions, etc. B. Easy Folding and Locking - To enhance safety, these brackets are equipped with spring-activated "latches" to ensure stability in the open position (please note that it locks in this position). When the table or work surface is not in use, simply press the latch to fold it up to free up more space. C. Load-Bearing Capacity - Each pair can bear 225 kilograms (500 pounds). These load-bearing limits are only general guidelines and do not constitute express or implied warranties. These brackets work well when applied to furniture legs or narrow and simple work surfaces. A wider spacing without leg support will reduce the load-bearing capacity. The load-bearing capacity under actual use conditions is usually lower than that under laboratory conditions. D. Parameters - Dimensions: See the picture. Material: Iron. Color: Black. Weight: 0.2 kilograms (0.4 pounds) per pair. Maximum load-bearing: 225 kilograms (500 pounds) per pair. E.
